Recently, I have been playing around with our XH A1 and direct-to-laptop recording via Adobe OnLocation CS4. If I record in SD mode, everything works perfectly. However, when I switch it over to HD, I start getting all kinds of artifacts in the footage whenever the camera moves slightly.

The laptop is a brand new Dell with an i7 1.6 processor, 6GB of ram and a 7200rpm SATA drive. Any ideas why I would be having problems properly record HD video?
